Re: Is my GTV running cold?
On a V6 it just a case of syphoning the expansion tank, removing the clamp from the radiator to thermostat housing hose, undo the three 11mm bolts on the thermostat housing and lift it off. (The thermostat is built into the housing). Then reverse the procedure, except I replaced the Alfa hose clamps with a jubilee clamp (about 45mm). Thermostat from EB spares comes with gasket and is about £20. A bit more involved on a TS I believe - I'm sure there are directions on here or the other forum if you search.
